          <h1 id="WelcometoProj4J">Welcome to <strong><i>Proj4Net</i></strong></h1>
      <p/>
<p>
<strong><i>Proj4Net</i></strong> is a .Net library to transform point coordinates from one geographic coordinate system to another, including datum transformations.
</p>
      <p><strong><i>Proj4Net</i></strong> is a direct port of <a class="ext-link" href="http://trac.osgeo.org/proj4j">Proj4J</a></p>
      <p>The core of this library is a port of the <a class="ext-link" href="http://trac.osgeo.org/proj/">PROJ.4</a> C library.
          The projection algorithms, concepts and coordinate system definitions are all taken directly from PROJ.4.
          These are wrapped in a C# class model which follows standard Java conventions and OO best practices.
      </p>
